Purpose: Three-dimensional (3D) video games played using virtual reality head-mounted displays (VR-HMDs) are becoming increasingly popular. However, the use of this technology may lead to visual symptoms and discomfort by disrupting normal linkage between accommodation vergence systems. This study aimed investigate effect playing 3D VR-HMDs on different oculomotor functions (i.e., and/or...

To explore the degree which attentional set in one task interferes with performance in a secondary task, we have developed a prototype SRRI test system. This comprises a central task involving driving through a virtual maze and the presentation of an intermittent stream of competing stimuli of varying levels of salience. Centrally presented arrows are followed in the driving task and the stream...

This paper describes a visual interface that recognizes the command request of a person by inferring the intention to travel in a desired direction at a certain speed from the person’s head movements. A rotation and a vertical motion indicate the intent to change direction and speed respectively. The context for which this solution is intended is that of wheelchair bound individuals. This paper...

We present a technique that allows users of video seethrough head-mounted displays to work at close range without the typical loss of stereo perception due to reduced nasal side stereo overlap in most of today’s
